LOCK.

Application `iled July 16, 1925.

This invention relates to locks and in particular to one which can be used in combination with a latch to serve `as an antijimmy agent or can be used separately to prevent `jirninying of the door or otherwise forcing `1t open from the outside.

.A particular object of the invention is to provide an auxiliary lock which comprises a 'separate locking bar which extends across 1"0 the meeting pointof the door and frame and engages a keeper plate in such manner as to prevent the opening et' the door should the same be forced away from the trame.

A "further object is to provide a lock of "It this character which will also lock the outer latch when the inner lock is placed in position and the tumbler barrel of the inner lock revolved after `locking said inner lock.

Referring to the drawing wherein I have shown a preferred embodiment of my invention:

Figure 1 is a view of the inside of a door showing my improved lock in locked position "26 Figure 2 is a partial view of the lock as seen in Figure 1, the locking lever being "shown in unlocked positidn to release the bar Figure 3 is a section taken on line 3-3 50 of Figure 1 and `shows the outer latch lock and its connections through the door with the inner bolt lock,

Figure 4 is a front view of the bar locking member showing the position of the lock plate or member in locking position,

Figure 5 is a section on the line 5 5 of Figure 4, the tumbler barrel being shown in full Figlire 6 is a view of the reverse side of the locking bar, the reverse side being the one `which is normally against the door;

Figure 7 is a section on the 4line 7-7 of Figure 6, the keeper plate on the frame of the door being shown in outline, and

Figure 8 is a section taken on the line 8-8 of Figure 3 showing how the lock is attached to the door.

Referring to the drawing in detail 5 indicates a portion of a door and 6 a portion of a door frame to the former of which is attached in the usual manner the latch 7 which is of any well known make employing the serrated key to operate a tumbler barrel combination7 the barrel being shown dotted as at 8 in Figure 3 and having' its end slotted in the usual manner to receive the Serial No. 43,922.

projecting linger 9 ot' an auxiliary lock barrel l() which forms a part of my present irnjjirovement. It is to be understood that no particular forni of lock is referred to as I may use any suitable key operated combination. F or illustration I make use of a lock which is key operated at one side oit' the door and in turn transmits the revolving motion of the tumbler barrel to another adjacent lock or latch on the opposite side of the door, so that both may be operated from one side of the door.

The auxiliary lock 11 thereforecomprises the barrel 10 which is held within a pin housing 12 which lits into a suitable bore 13 in' the door 5, the barrel 10 being held in the housing through the medium of a disk 14 secured thereto by screws 15, the disk edge overlying the edge of the housing 12, while the opposite end of the barrel eX- tends into a cup-like locking member 16 and has cast integral therewith a lock lever 17, the ends of which are cut on a radius to tit and operate within the overturned edges 18 of the lock bar 19 as shown in Figure 7; when the barrel 10 is revolved by a key which is inserted `in the keyhole 20 in the end oi' the same and adjust the tumblers or pins 21 shown in dotted lines in Figure 3 so that the barrel can be revolvedI by the key. The disk 14 carriesthe projecting finger 9, above referred to, sothat any movement of the barrel 1() is conveyed to the barrel 8 of the latch.

The housing 12 may be east integral with the cup locking member 16 and has at its inner end the wings 22 through which pass the screws 23 which engage a plate 24 which bears against the opposite side of the door to hold the lock in position, the tightening of the screws serving to compress the wood of the door lietween the plate 24 and the cup-like locking member 16, as shown in Figure S.

It will be evident therefore, that a revolving movement of the barrel l() through the medium ot an inserted key will revolve the lock lever 17 to engage its ends within the turned over edges 18 of the lock bar 19, and a further revolving movement of the key will operate the lock on the other side of the door.

The lock bar 19 it will be noticed has its end enlarged as at 25 to snugly fit within the cup-like locking member 16, the turned over edges of the barbeing normally ai ranged around the top and bottoni and be ing spaced at their ends substantially the width of the lock lever 17, so that when the lock lever is horizontal the lock bar 19 can be drawn or lifted ont ot the locking member While its opposite hooked end 2G can then be drawn out of the opening,` in keeper plate 27.

It desired the auxiliary lock can be used alone, as it Will prevent any jimmying ot the door or spret'idinp; ot the tramet and in this case the Wings 22 of the barrel housing together with the plate 24: can be dispensed with and as shoivn in Figure the door can be provided with a Well or bore 28 into.- Which tits the barrel housing Q9, the cup-like looking member being` provided With openings through which screvvs 30 may pass Vto hold the locking member in position against the door..

The lockv bar 19 is provided with an opening 31 through which passes the end of the barrel 10 4When the bar 19 is in position in the locking member 16,

It will be evident that the door is securely7 locked when the lock lever 17 is in vertical position With its ends engaging the end of the lock bar 19 and a further locking movement ot the barrel 10 also locks the other latch.

It is evident therefore that I have provided a means ,for locking both sides ot a door from one side thereof and also a locking member which prevents separation ot the .door and frame as is usual When a door is jimmied. Also by providingr a stoutlocking bar it makes it almost impossible to enter unless the proper key is used to release the locking bar.

Having described my invention what I claim is:

1. A lock arrainrement for doors consisting oit' a latch lock adapted to he positioned on one side of the door, and a har lock at the opposite side olf the door, said bar lork comprising a receptacle, a lock lever there-- in, a separable ba* adapted at one end 'to engage said lock lever and at'y its other end to engage a keeper plate, and means tor locking` said lock lever, .said ineansI heine' also operable to lock the latch on the opposite side of the door.

2. The combination with a door having an opening" therein ot a latch loch on one Side otl said door, a. bar receiving and lot-hing' receliitacle on the opposite side ot said door, a locking' lever therein, meansV for operating said lorkins;` lever,y said means er tending `into said oliienine', and :in extended portion on said operating meam `for engage ing; said'latch lock whereby the latter if-l: operated by the lockingr lever operating: means.

3. A loeli eominieinir :i` enp-li| e rerel'itaele portion and an extended portion the latter beingr adapted to lit. into an opening); in :i door, a locking' level' in said receptacle, :l bar having an enlarged end adapted to lit into said receptacle and be locked therein by the locking,r lever, and the other end o'l" said bar being bent, and a keeper plate through which said bent end ot the bar is passed.

ft. A lock arrangement for doors consisting otl a latch lock on one side ol the door, a bar lock at the opposite side ot the door, latch lock operating means on the said bar lock, and a keeper plate and an ant1ijimmy agent associated with the keeper plate and the said latch lock operating` means.
